Frank:

There is, or at least was, a problem writing to the EEPROM using the
PICSTART Plus in MPLAB.  If you are using that combination, try going
to the Options menu, select Development Mode and check the Editor Only
box.  In the edit only mode, the data seems to get written to the device
correctly.  Otherwise, the EEPROM is all 'FFh'.  It was still that way
with MPLAB 3.09.10.  I haven't tried the latest version.
